I managed to start Biomutant with the g3d and the direct vr (but is it needed?) With the Conarium profile. I uploaded the profile to the cloud. obviously it is temporary, finish configuring it according to your needs!
but it’s very taxing, it’s not smooth on my rtx 3090.
you can tweak those settings to get better fps and if you dont want dynamic shadows just set r.shadowquality to 0 you will still have static shadows and better fps with no glitch.
i had to tweak the profile btw to get rid of some decal glitch, did you do that as well ?
